Title: Foaming flux for automatic soldering process
Inventor: TURNER RAYMOND L
IPC: B23K35/363
Filed: 1992-10-15
Granted: 1997-07-22
Abstract: A non-toxic, non-corrosive foaming soldering flux (14) comprises citric acid and water, together with at least one foaming agent.  The foam is fast-breaking, dissipating almost immediately.  Such a fast-breaking foam is novel in an aqueous-based flux.  The unique flux of the invention produces solder joints of high metallic luster and excellent quality.  Disposal presents no health hazards, and clean-up of flux residues is accomplished using only water and, optionally, a surfactant.

Title: Apparatus for producing croissants with a filling
Inventor: MORIKAWA MICHIO
IPC: A21C9/06
Filed: 1993-01-05
Granted: 1995-08-15
Abstract: This  invention  provides  an  apparatus  for  producing croissants  with  fillings.   The  apparatus  comprises  a filling-depositing means, a rolling-up preparation means, and  a  rolling-up  means.   Since  a  dough piece  with  a filling on it is rolled up by the rolling-up preparation means before it is conveyed to the rolling-up means, the filling  does  not  flow  out of  the  dough  piece.   Thus croissants can be continuously produced without failure.

Abstract: A method and system for increasing the speed at which test answers are processed. The system receives electronic representations of test answers and organizes the test answers into separate groupings. The system next displays a particular grouping of test answers to a test resolver so that the resolver can score the test answers. In displaying the answers, the system uses a matrix of cells and displays one test answer in each of the cells. The test resolver can thus simultaneously view multiple test answers, which facilitates efficient scoring of the answers.

Title: Carrier detector
Inventor: SOGABE YASUSHI
IPC: H04L27/00
Filed: 1994-01-18
Granted: 1999-03-16
Abstract: A carrier detector which is capable of performing high-accuracy carrier detection even with patterns other than a carrier recovering (CR) pattern by processing signals on the frequency axis, regardless of the existence of the residual frequency due to the quasi-coherent detection.  The carrier detector converts a received signal having been subject to the quasi-coherent detection, A/D conversion, filtering for eliminating noises and expressed on the time axis into that expressed on the frequency axis by the time axis/frequency axis converting circuit.  An accumulator 2 accumulatively adds the signals expressed on the frequency axis, and a decision section compares the accumulated value output from the accumulator to a predetermined threshold to detect the coming of the burst so as to detect the carrier.

Title: Use of borate-polyol complexes in ophthalmic compositions
Inventor: CHOWHAN MASOOD
IPC: A61K9/00
Filed: 1993-05-04
Granted: 1999-01-05
Abstract: Water-soluble borate polyol complexes are useful as buffers and/or antimicrobials in aqueous ophthalmic compositions, including those containing polyvinyl alcohol. These compositions have greater antimicrobial activity than comparable compositions containing typical borate buffers and unexpectedly increase the antimicrobial efficacy of other antimicrobial agents when used in combination. In addition, use of the borate-polyol complexes avoids the incompatibility problem typically associated with the combination of borate buffer and polyvinyl alcohol; therefore, the compositions disclosed herein may also contain polyvinyl alcohol.

Abstract: Thixotropic Fuller's earth clay minerals which are structurally double silica chains linked together through oxygen to form double-ribbed sheets held by aluminum and/or magnesium in octahedral coordination in an amphibole chain are vacuum dried and admixed with a stabilizing fluid, e.g., silicone fluid, to result in new, low moisture content thixotropic agents. The mineral products thus produced are superior thixotropes when compounded in plastics such as plastisols, adhesive sealants, coatings and other organic binder systems which are heat set or heat cured or moixture cured, and compliance coatings. The methods involve reducing the moisture content of Fuller's earth clay, e.g., attapulgite, by (1) heating it under vacuum at an elevated temperature, preferably between 100 °C and 300 °C, or (2) heating it at an elevated temperature, preferably between 100 °C and 350 °C, and adding a stabilizing fluid, or (3) heating it under vacuum at an elevated temperature, preferably below 300 °C and adding a stabilizing fluid, to preserve its low moisture properties.
